Prevalence of Critical Errors and Insufficient Peak Inspiratory Flow in Patients Hospitalized with COPD in a Department of General Internal Medicine: A Cross-Sectional Study.

Background: The suboptimal use of inhalers in the treatment of patients with chronic obstructive pulmonary disease (COPD) is probably a major but poorly documented problem in hospitalized patients. We aimed to describe the prevalence of misused inhalers among patients hospitalized with COPD in a department of general internal medicine. Methods: We conducted a monocentric cross-sectional study in consecutive patients with a diagnosis of COPD and hospitalized between August 2022 and April 2023 in the internal medicine division of Fribourg Hospital, Switzerland. Patients underwent an assessment of their inhaler technique and peak inspiratory flow (PIF) using the In-Check Dial G16®. The primary outcome was the prevalence of misused inhalers, defined as an inhaler used with a critical error and/or insufficient PIF. Secondary outcomes included the prevalence of inhaler unsuitable to patient characteristics and of patients using at least one misused inhaler. Results: The study included 96 patients and 160 inhalers were assessed at admission. Among these inhalers, 111 (69.4%; 95% confidence interval [CI] 61.6-76.4) were misused; 105 (65.6%; 95% CI 57.7-72.9) due to the presence of a critical error in the inhalation technique and 22 (13.8%; 95% CI 8.8-20.1) due to insufficient PIF. Concerning the secondary outcome, 27 inhalers (16.9%) were unsuitable and 79 patients (82.3%) used at least one misused inhaler. Conclusion: Among patients hospitalized with a diagnosis of COPD, two-thirds of inhalers were misused. Suboptimal use was mainly due to the presence of critical errors, but also to the presence of an insufficient PIF and unsuitable inhalers.

An in-hospital intervention to reduce the proportion of misused inhalers at hospital discharge among patients with COPD: a non-randomised intervention study.

AIMS OF THE STUDY: Misuse of inhalers during chronic obstructive pulmonary disease (COPD) treatment is common and may result from errors in inhalation technique or insufficient peak inspiratory flow (PIF). We aimed to evaluate the impact of an in-hospital intervention to reduce inhaler misuse at hospital discharge among patients with COPD. METHODS: We conducted a monocentric, non-randomised intervention study to compare the proportion of misused inhalers at hospital discharge by patients with COPD between a group with standard care and a group receiving an in-hospital intervention. The control group successively included all patients hospitalised between March and June 2022, and the intervention group included patients hospitalised between August and December 2022. The intervention consisted of (a) an evaluation of inhalation technique and PIF at admission, (b) the provision of a written guide to assist in the selection of an inhaler, and (c) therapeutic education. The primary outcome was the proportion of misused inhalers, defined as an inhaler used with a critical error and/or insufficient PIF, at hospital discharge. The primary outcome was assessed by observing inhalation technique and measuring PIF using the In-Check DIAL G16® . RESULTS: The study included 93 patients: 46 in the control group and 47 in the intervention group. Mean age was 70.5 years (SD 10.9 years), 56 patients (60.2%) were men, and 57 patients (62%) were hospitalised for a COPD exacerbation. Patients used an average of 1.9 inhalers at hospital discharge; 98 inhalers were assessed in the control group and 81 in the intervention group. The proportion of misused inhalers at discharge was 61.2% in the control group and 21.0% in the intervention group (absolute risk reduction 40.2% [95% CI 25.5-55.0]; p <0.01). In the intervention group, the proportion of inhalers used with at least one critical error was reduced by 38.6% (95% CI 24.3-52.3%) and that of inhalers used with insufficient PIF by 13.9% (95% CI 4.2-23.6%). CONCLUSIONS: An in-hospital intervention was associated with a reduction in the proportion of misused inhalers at hospital discharge. This intervention should be considered for hospitalised patients with COPD. The trial was registered with ClinicalTrials.gov (NCT05207631).

Left hepatic hydrothorax without ascites.

Hepatic hydrothorax (HH) is a complication in patients with cirrhosis and portal hypertension. It predominantly presents in the right pleural cavity and usually associates with ascites. Few cases of HH occurring without detectable ascites have been reported. This case report comprehensively presents a case of a refractory left unilateral HH without ascites. The patient benefited from palliative care and the HH was managed using a semipermanent indwelling pleural catheter until she died 3 months after diagnosis.

Survey of dietary beliefs and habits of inflammatory bowel disease patients.

BACKGROUND & AIMS: It is presumed that diet plays a role in the prevention and pathogenesis of inflammatory bowel disease (IBD). Patients with Crohn's disease (CD) and ulcerative colitis (UC) often report a link between their disease and diet. However, studies evaluating patient perceptions on diet in IBD are lacking. This study aimed to assess patient beliefs on the role of diet in IBD and the adequacy of dietary advice they received. METHODS: A self-administered questionnaire was offered to consecutive patients attending two IBD centers in Switzerland. Data were collected regarding patient dietary beliefs and behaviors and whether they received medical advice on their diet. RESULTS: Of 210 questionnaires distributed, 171 were completed. Participants were mainly female (53%), young (median age 38 years) with either CD (66%) or UC (34%). Most patients believed that diet plays a role in their disease (74%), whereas only 15% believed that diet could be the trigger of their disease. Since their IBD diagnosis, more than half of patients (56%) modified their diet, and 39% did not receive dietary advice from their physicians or a dietician. Most patients (91-95%) ingested gluten, lactose, red and white meat. 20% of patients practiced intermittent fasting and only a minority had previously tried a low-FODMAP (9%) diet or probiotics supplementation (16%). CONCLUSION: The majority of IBD patients believe that diet plays a role in their disease but have never received dietary advice from their doctor or a dietician. This highlights a need for more information for IBD patients on dietary advice from the medical profession.

Patient Characteristics to Consider When Selecting an Inhaler for the Treatment of Chronic Obstructive Pulmonary Disease and Available Assessment Methods: A Narrative Review.

Inhaler misuse is common among patients with chronic obstructive pulmonary disease and associated with poor disease control. Many patient characteristics are reported to impact inhaler use, but there are no studies in the literature on the best way to evaluate them. This narrative review aims to identify patient characteristics that influence the correct use of an inhaler and describe the tools available for their assessment. First, we searched four different databases to identify reviews describing patient characteristics reported to impact inhaler use. In a second step, ways to characterize these aspects were searched using the same databases. Fifteen patient characteristics impacting on the use of inhalers were identified. Peak inspiratory flow, dexterity, and cognitive impairment were the most studied characteristics and appeared to have the highest impact on the correct use of inhalers. Notably, peak inspiratory flow can be reliably assessed in clinical practice using the In-Check Dial®. Triggering coordination, breath retention, collaboration/consciousness, and muscle strength in the fingers were important characteristics, but insufficient data exist to recommend the use of a specific tool for their assessment in daily practice. Other identified characteristics have a more uncertain impact. A demonstration of inhalation technique by the patient, combined with the measurement of peak inspiratory flow using the In-Check Dial®, appears to be an effective strategy to assess the characteristics with the highest impact on the correct use of an inhaler. In the future, "smart" inhalers could also play a decisive role in this area.

[Communicating uncertainty: a necessary harm?] / Communiquer l'incertitude : un mal nécessaire ?

Uncertainty is omnipresent in medical practice. It occurs when the available data do not allow predicting with accuracy the patient's outcome. Paradoxically, despite the exponential progress of medical knowledge, uncertainty in medical practice seems to increase. Even though uncertainty is present at every stage of medical practice, this uncertainty is rarely discussed with the patient. However, there is an ethical and legal necessity to communicate it with the patient. The aim of this review is to describe the barriers and impacts of the communication of uncertainty with the patient and suggest strategies to enhance its communication.

L'incertitude est omniprésente dans la pratique médicale. Elle apparaît quand les données à disposition ne permettent pas de prédire avec exactitude le devenir du patient. Paradoxalement, malgré l'augmentation des connaissances médicales, elle semble s'accroître dans la pratique médicale. Bien que présente à chaque étape de la prise en charge du patient, cette incertitude est peu discutée avec lui. Cependant, il existe une nécessité éthique et légale à sa communication avec le patient. Cet article a pour but de décrire les barrières et les conséquences de la communication de l'incertitude avec le patient et de proposer des stratégies pour améliorer sa communication.

[How To Teach Uncertainty Management]. / Pédagogie de l'incertitude en médecine.

In this article, we propose a model to teach uncertainty management. Our primary goal is to define the concept of uncertainty and its stakes. We then discuss the effect that uncertainty may have on physicians and patients. We finally present reliable strategies to address medical complexity and how to teach or assess complexity management.

L'objectif de cet article est d'apporter des pistes pédagogiques permettant d'enseigner la gestion de l'incertitude en médecine. En premier lieu, il s'agit de formuler une définition du concept d'incertitude afin d'en comprendre les enjeux. Nous discuterons également des conséquences d'une mauvaise tolérance de l'incertitude pour le médecin et pour le patient. Enfin, nous verrons différentes stratégies qui permettent de mieux appréhender la complexité des situations médicales et quels pourraient être les moyens d'enseigner ou d'évaluer l'incertitude.

[Adherence to inhaled therapy in adult patients affected by asthma or COPD]. / Adhérence aux traitements inhalés chez les patients adultes atteints d'un asthme ou d'une BPCO.

Inhaled treatment is the cornerstone of drug treatment for the two most common chronic obstructive respiratory diseases: asthma and chronic obstructive pulmonary disease (COPD). Therapeutic adherence is essential in the management of any chronic disease. In real life, only one-third of adult patients with chronic obstructive pulmonary disease have "good adherence". In this article, we will define therapeutic adherence before describing ways to assess and improve it in patients receiving inhaled therapies.

Le traitement inhalé est la pierre angulaire de la prise en charge médicamenteuse des deux maladies pulmonaires chroniques obstructives (MPCO) les plus fréquentes : l'asthme et la bronchopneumopathie chronique obstructive (BPCO). Comme dans toute maladie chronique, l'adhérence thérapeutique est primordiale. Dans la vie réelle, seul un tiers des patients adultes souffrant d'une MPCO présente une « bonne adhérence ¼. Dans cet article, nous définirons l'adhérence thérapeutique avant de décrire les moyens de l'évaluer et de l'améliorer chez les patients bénéficiant de traitements par inhalation.
